Yeah, I agree. You can tell that arc was kinda rushed compared to the others and people didn't understand what character development was back then (even today they still don't). Fullbring arc is like my 2nd or 3rd favorite arc in the series. I liked that there was less fighting, but more about Ichigo's struggle of losing his powers and how that affected him. He might've wanted a powerless life at first, but after all he went through, he was definitely having conflict.
I also liked how he genuinely wanted to kill Tsukishima, compared to just beating the rest of his opponents because he had to. This desire to kill was so much more personal and it was completely different than what we saw from Ichigo before. CFYOW does provide context for Ginjo and Fullbringers and just shows how the Soul Society is basically responsible for almost all the mess that goes on in the series lol.
